CD14 inhibition efficiently attenuates early inflammatory and hemostatic responses in Escherichia coli sepsis in pigs.

ABSTRACT: Sepsis is a severe infection-induced systemic inflammatory syndrome. Inhibition of downstream inflammatory mediators of sepsis, e.g., TNF-alpha, has failed in clinical trials. The aim of this study was to investigate the effects of inhibiting CD14, a key upstream innate immunity molecule, on the early inflammatory and hemostatic responses in a pig model of gram-negative sepsis. The study comprised two arms, whole live Escherichia coli bacteria and E. coli lipopolysaccharide (LPS) (n=25 and n=9 animals, respectively). The animals were allocated into treatment (anti-CD14) and control (IgG isotype or saline) groups. Inflammatory, hemostatic, physiological, and microbiological parameters were measured. The proinflammatory cytokines TNF-alpha, IL-1beta, IL-6, and IL-8, but not the anti-inflamma
